Application filed July 18,

This invention relates to improvements in car construction.

In the operation of railroads it has been found advisable to lock the undenframing and trucks of the car together so as to ruin imize or prevent overturning or telescoping of the cars in event of collision or derailment, and certain types of split locking pins have been utilized for'securing the trucks against vertical separation with reference to the underframing of the car; Incertain I types of railway equipment the car construc tion is of such character as to prevent insertion of the locking king pins from the top of the under-framing, and the same must be inserted from below the truck bolster.

An object of the present invention is to provide car construction in which the underframing and truck bolster are so arranged as to accommodate a locking kingpin inserted from beneath the truck bolster, in conjunction vwith a locking pin of the split type including flanged sections and a spread er, which latter elements are provided with detachable means for maintaining the spreader between the flanged sections in such position as to lock the under-framing and truck bolstertogether, and wherein the detachable means is accessible from "beneath the truck bolster to permit the ready applicationand removal of said pin.

A. more particular ob 'ect of the invention is to provide a construction of the character 7 referred to, wherein the flanged sections of the locking pin, and the spreader, are held in operative position through the medium of detachable fastening elements which have abutments adapted to engage portions of the flanged sections forming part of the pin, wherebysaid sections are prevented from spreading apart, and the fastening elements are held against movement in a direction to accidently detach the same, the construction being such that the weight of the spreader is imposed upon the fastening elements and serves to maintain the abutments of the fastening elements and the flanged sections in operative position. I

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming part of this specification, Figure 1 is a fragmentary transverse sectional view through the center sills,

of the lower end of'the pin shown in Figure 1. and illustrating a slightly different embodiment of the invention.

In the drawings, portions of the center sills of the car are shown, each of the same comprising a vertically disposed plate 10, having angle members 11-11 secured to the slower outer edges thereof, and having oppo- V sitely disposed angle members 1212 secured to the lower inner edges thereof. A body bolster is provided, comprising the usual top and bottom cover plates, the lower of which is indicated at 13, said plate having a central opening 14: adapted for the reception of the.

upper annular flange of the center plate 15 which is secured to the under-surface of the plate 13. The center plate is provided with an opening 16 for the passage of the king pin hereinafter described. Disposed be tween the center sill plates 10-10 is a filler casting" indicated at 17, said filler casting being provided with a center pin section 18 whi ch has cylindrical walls closed at the top, andan annular off-set adjacent the bottom providing a shoulder 19 which surrounds an opening 20 through which the king pin is adapted to pass. f

The truck bolster is indicated at 21, and for themost partis of the usual hollow cast steel construction including "a top wall 22 provided with a center plate section 23 adapted to accommodate the annular rib on the center plate 15 secured: to the body bolster cover plate. a central pin section 24 having an opening thercthrough for the passage of the king jpin, and being off-set adjacent its bottom to i provide an. annular shoulder 25. he lower somewhat enlarged chamber 26 openingoutwardlybeneath the truck bolster. A fragment of the; spring plank of the truck is indicated at 126, said plank being provided with an opening 127 through which the lock in) Said bolster also includesju ing pin hereinafter described may be inserted when said pin is belng inserted into operative position. The locklng pin is of a sectional two-piece split type and comprises two side members -2727, each of which is I of approximately sem1c1rcular cross section,

' adapted to engage the annular shoulder in the center section 24 of the bolster 21 in certain position of the parts. The ends 30 of the sections 27- 27 arecach provided with an ear 31, and each'ear has a longitudinally extending slot 32 formed'therein,

the lower end of the slot merging with an offset 33, the ears 31 being alike except for Co-operating with the sections 27-27 of the pin is a spreader 34, the latter being in the form of their opposite disposition.

a flat bar adapted to beinserted between the sections 27-27 to spread them apart after they are inserted upwardly through the cen ter pin sections so that the flanges 28-28 inter-engage with the annular shoulder 19' of the section 18, while the flanges 29--29' are disposed in line with theannular shoulder 25 to prevent separation of thetwo center sections of the body bolster or underframing of the car and the truck bolster respectively. The lower end of the spreader 34 is provided with a longitudinally extending slot adapted to register with the slots 32 in the ears 31 incertain positions of the a parts. This spreader 34 is supported from its lower ends by means of a fastening mem ber 36. bald fastening member comprises a cylindrical central section 37, and spaced angularly disposed arms 3838,said fastening member 37 being insertable from one side of the ears 31, through the slots 32 of said ears, and the slot 35 of the spreader when said slots are in register, the fastener being moved downwardly to engage the arms 38-38 inthe off-sets 33fof said ears, and" being held in positionby the weight of the spreader 34, and at the same timeysnpporting the spreader 34 againstdropping out from its spreading position between the pin sections 27- 27," Due to the arrangement of the off -sets 33, the outer surfaces of the fasteningelement are disposed flush with the ontersurfaces of the cars 31, and

said fasteningmember effectually maintains the sections 27 against spreading movementwhich n'nght-serve to disconnect the same. I In the use of the invention, when it 1s desired to remove the locking pin access mav i be gained to the fastening member 36, the

spreader slightlyelevated so as to permit (isconnection of the arms 38-38 with the" cars 31, after which the fastening member when it is ,desiredto' may be removed'laterally with reference to the locking pin, and the spreader dropped downwardly permitting the sections 27-27 flanges 28 from the shoulder 19, after which said sections may be removed, the spring plank being provided with the opening 127 to permit ready removal of the parts. In

applying the pin the sections 27 are placed together and inserted into the bearing openings from underneath the bolster until the flanges are in position to engagethe shoulder19, after which the spreader is inserted, "with the slot 35 registering with the slots 32 of the ears31,*the fastening member 36 being then insertedand the spreader released to impose its weight upon the fastening member which maintains the arms thereof in interlocking engagement with the off-sets 33.

' Referring to Figure "4, the ears40-40 of the in sections 41 -41 are similar, in form 'to t e ears 31 above described, except the slotsf42-42 insaid ears are of plain elongated form with no ofi-setc0rresponding to the off-set 33 heretofore described. The

" spreader 43 is provided with an elongated to be moved together soils to disengage the slot 44 adapted for the reception offlthe i fastening member 45. The fastening member 45comprises a cylindrical body portion 46, the ends of which are disposed in the slots 4242, while the cylindrical'portion intermediate its en ds 'extendsthrough the slot 44 in ,the spreader 43 and is provided with a laterally disposed projection 47 which fits in the slot 44, and whichis disposed between theearsi40 40, where it is held in position under"v the weight of the spreader 43 hearing thereon, accidental detachment of said fastening member laterally of the ears 40-40 being thus prevented.

The 1 operation of the construction just ion described is essentially similar to that re- 7,

ferredto in the construction shown in Figures 1 to 3 inclusive, the fastening member being held in position under the influence of the weight imposed thereon by the spreader, and being removable when the spreaderis elevated and the lateral extension 47 is lifted'from its position between.

the lower ends of the ears 4040. Inap plying the fastening member, the slots in the ears 4040 and spreader 43 are lined up, the fastening member inserted and the lateral projection dropped between'the ears 40 40 where rit is held by'the' spreader, thereby effectually preventing: accidental detachment of the fastening member, but permitting the same to "be readily detached its locking position. i
